中国南方海南鳽收容救护状况调查分析

Rescue Status of White-eared Night Heron(Gorsachius magnificus) in South China

采用网络和发函调查的方法,对中国动物园、自然保护区、野生动物救护中心1998-2012年间非正常来源的海南鳽的收容救护现状进行了调查。结果表明：中国9个省份的21个市（县）在这期间共救护海南鳽36次42只,平均每年救护2.4次2.8只个体,年救护数量呈总体上升趋势。海南鳽80%以上的救护数量集中在4-10月,以幼年和亚成体为主,约占71.4%（30/42）。经过救护之后,73.8%（31/42）的个体能恢复健康并被直接放归野外或用于科普和科研工作。非法捕猎、疾病和身体虚弱是导致海南鳽受困的主要原因。在救护过程中,严重外伤、营养衰竭和寄生虫病是导致海南鳽死亡的主要原因。食物短缺是引起其濒危的重要因素之一。
